                                        공진주파수

 

;                                              측정모드

콘크리트 시험체가 갖고 있는 고유의 공진주파수[Resonant Frequency]를  비파괴적으로 측정해내, 그 재료의

 탄성계수[Dynamic Modulus of Elasticity], 경도계수[Dynamic Modulus Rigidity], 및 동프와송비[Dynamic Poission's  Ration] 등을 산출해 낼수 있는 장비입니다. 특히 기존의 검출방식과는 달리,  자체 비교 회로에 의해 공진주파수[Resonant Frequency]를 검출해 내고 재료의  감쇄상수 'Q'값을 자동계산 및 모든 측정 데이타 값을

자동 저장합니다. ASTM 규정된 시험체에 대한 3축[3軸] 방향으로의 측정이 가능하여 조건에 적합한 시험을 수행

할 수 있습니다.
